People can be killed in ways that are difficult to trace, especially before there is the benefit of autopsy results.
I am not suggesting that this is what happened in this case, I'm just saying that it is far from entirely ruled out.
They probably just didn't see any drugs lying around. If he didn't have some sort of undiagnosed medical condition, he may have very well OD'd on something. Research chemicals, xanax and opiate combo, etc... It's fairly common for people to OD on those things and they're all readily available.
Hard to believe it takes so long in the 21st century. Is that bureaucracy or science?
To give an anecdotal story. I use Diazepam to control muscle spasms and cramps caused by a neurological disorder.
I took my kids to an amusement park and took Dramamine (over the counter motion sickness medication) so I wouldn't get sick on the rides. About 20 minutes later I was a complete zombie, so bad I sat down and could not get back up because I was in such a stupor.
Turns out these two drugs have some serious interactions with each other, including sudden death and heart failure. To this day I consider myself lucky.
